Find Profitable Stocks

Screen and analyze stocks based on free cash flow and fundamentals to identify truly profitable companies with health scores and key metrics.

Security Scan

The skill is instruction-only and its requirements (internet access, Python + requests, and calling East Money public APIs) are consistent with its stated purpose of screening stocks by free cash flow and fundamentals.

Purpose & Capability

Name/description (screening by FCF and fundamentals) align with the instructions which fetch financial data from public APIs and compute health scores; nothing requested is unrelated to stock screening.

Instruction Scope

SKILL.md explicitly limits actions to fetching public market data (push2.eastmoney.com), computing scores, and returning metrics. It does not instruct reading local files, collecting unrelated system data, or sending data to third parties beyond the listed public API.

Install Mechanism

No install spec (instruction-only). The declared runtime requirements are minimal (Python 3.x and requests); no downloads or installers are specified, so nothing will be written to disk by the skill itself.

Credentials

The skill requests no environment variables, credentials, or config paths. That is proportionate to its purpose; public API access and demo fallback are described without asking for secrets.

Persistence & Privilege

always is false and the skill does not request permanent presence or system-wide config changes. Autonomous invocation is allowed by default but is not combined with other red flags.

Assessment

This is an instruction-only stock-screening skill that uses public East Money endpoints and falls back to demo data when offline. Before installing: ensure the agent environment has internet access and Python + requests available; understand that the skill will query public financial APIs (push2.eastmoney.com) so check any applicable data usage or licensing terms if you use results for commercial/trading decisions; the skill does not request credentials or access local files, but you should still verify outputs and not rely solely on automated scores for investment decisions. If you require other data sources (e.g., US exchanges), confirm the skill supports them or adjust accordingly.

SKILL.md - Find Profitable Stocks (自由现金流掘金)

Description

Find truly profitable companies using Free Cash Flow (FCF) and fundamental analysis strategy.

Free Cash Flow = Operating Cash Flow - Capital Expenditure

This skill screens for companies that generate real cash profit, not just accounting earnings.

When to Use

• User asks "find profitable stocks"
• User asks "free cash flow analysis"
• User asks "真正的赚钱公司" / "现金流好的股票"
• User asks "筛选优质股票"
• User wants to analyze a specific stock's cash flow quality

How It Works

1. Fetches financial data from public APIs (East Money / Sina / Tencent)
2. Calculates health scores based on:
   • Valuation (PE/PB)
   • Profitability (ROE, profit margin)
   • Growth (revenue/profit growth)
   • Technical (price action, volume)
3. Ranks and outputs results

Usage

Analyze a single stock

分析 600938 的基本面
筛选 股票 159201

Screen for profitable stocks

• Health Score (0-100)
• Grade (A/B/C/D)
• Key metrics (PE, ROE, growth, etc.)
• Analysis summary

Data Sources

• Primary: East Money API (push2.eastmoney.com)
• Fallback: Demo/Mock data (when network unavailable)
• Note: Requires internet access for real-time data

Requirements

Status

Ready for use - Network dependent (will show demo data if offline)
